JavaScript onPreSave Function Example 3: Checking a Parent

A quotation is entered in this example. The quotation has a parent Account, which contains a Customer Type keyword to indicate whether the customer is a preferred or a standard customer. Users are allowed to enter a discount if the customer is a preferred customer only. To perform this query, this example makes the following assumptions:

The parent account MODULEID is 2.
The MEFIELDNAME for the Customer Type field in the parent account is ACCTKW05.
The possible values in Customer Type keyword are Preferred or Standard.
The MEFIELDNAME for the Discount field is CUSTTXT07.

The query in this example is based on the code used in onPreSave example 1:

<html><head><title>PreSaveExample1</title><script type="text/javascript"> 
function fieldsOnPreSave(){ return "TASKDT01,TASKDT02"; }
function onPreSave(due,planned){ 
	if( due > planned ) {
		return true; 
	}else{ 
		window.location = "melt://showAlert/$due.greater.than.planned"; 
		return false; 
	}
}
</script></head><body></body></html>

The complete code for onPreSave example 3 with header and footer information is as follows:

<html><head><title>PreSaveExample3</title><script type="text/javascript"> function fieldsOnPreSave(){ return "CUSTTXT07,2.ACCTKW05" }
function onPreSave(discount,custtype){ 
	if(discount==0 || custtype=='Preferred'){
		return true; 
	}else{ 
		window.location = "melt://showAlert/You can only enter a discount for Preferred customers"; 
		return false; 
	}
}
</script></head><body></body></html>

For onPreSave example 3, the following changes are made to onPreSave example 1 code:

The fieldsOnPreSave function is changed to read the field in the current object and the field from the parent as follows: "CUSTTXT07,2.ACCTKW05"

Different names are used for the fields by changing the onPreSave function to the following: onPreSave(discount,custtype)

Two checks are performed: to return a true value if the discount is equal to zero (discount == 0), and to return a true value if the Customer Type is Preferred (custtype=='Preferred') since preferred customers are allowed a discount. Both queries are combined by using an OR query with a double bar or pipe symbols (||) as follows: { if( discount==0 || custtype=='Preferred') { return true ;}

The message that is displayed when the condition is not met is changed, and a False value is returned preventing the record from being saved as follows:

window.location = "melt://showAlert/You can only enter a discount for Preferred customers"; return false; }
